@cmb2022 Yes, that's so difficult to have a good day followed by a night without good sleep. That has to be terribly frustrating when you know you will be back at work today. It's good you don't feel you need to hide how you are feeling and that your supervisor is understanding. It sounds like you and I are alike in how we push ourselves with high expectations. It reminds me that doing your best can mean different things at different times. Today you are doing your best by going to work and listening to what your body is telling you.

Those new books will await you when you are ready.
